oke so here is my issue:

I have downloaded mirrorblend and installed the two scripts in the script folder that is located in my profile:

C:\Documents and Settings\xxxxx\My Documents\Maya\5.0\scripts

Start up maya and in the command line I type in: MirrorBlendSetup;

and now I get the error:

// Error: Cannot find procedure "MirrorBlendSetup". //

Is the location correct to install scripts ??
